Default [Q] Merge License Key with APK

The company I work with is looking toward using our MDM software to push out apps to our users, but the apps require a license key (that we would rather not confuse our users with having to input). Is there any way we can merge the license key into the APK so as soon as it's installed, it's licensed to us?
